7. Do you know that female orangutan prefer the males with bigger check-pads?

Mature male orangutans have large flappy cheek-pads, known as flanges, which frame their faces and make their heads look larger. In captivity, males as young as 13 years old develop cheekpads, but in the wild, some males may not grow them until the age of 30. Once a male has his cheekpads, he won't tolerate any other adult males in his vicinity and competes with them for access to receptive females. Cheekpads may also serve an acoustic function in helping project the 'long call' a male uses to broadcast his presence through the dense forest. [End]

Yes I know. Female orangutans love big strong males

Came across a fully flanged male whilst trekking through the jungle in Sumatra last month. He was so utterly breathtaking, I cried! 😊
